Which statement best describes how sarcopenia contributes to age-related risk?

• A. It leads to decreased muscle strength and gait instability, increasing fall risk.
• B. It increases muscle strength and reduces fall risk.
• C. It only affects cardiovascular health, not risk of falls.
• D. It improves balance with age.

Answer: (A)

Sarcopenia is the age-related loss of skeletal muscle mass and strength. As this muscle decline progresses, the ability to generate force and control movement diminishes, leading to slower, less stable gait and impaired balance. That combination directly raises the risk of falls, a major source of injury and decline in older adults.

So the statement that best describes its contribution to age-related risk is that it leads to decreased muscle strength and gait instability, increasing fall risk. Falls can lead to fractures, hospitalization, and a loss of independence, which underscores why sarcopenia is a critical factor in aging-related health risk. The other ideas—muscle strength increasing, only affecting cardiovascular health, or improving balance with age—do not align with how sarcopenia actually affects the musculoskeletal system and functional safety.
